(Cl. 164-59) Rotaryveneer is manufactured in sheets or will yield under the influence of acurled or strips of considerable and indeterminate lengths. warped edgeof the flimsy veneer. It is necessary to out these strips into widthsThe veneer is fed in the direction of the arrow suitable forincorporation in plywood, and this A from a feed table I past a clippingknife 2 5 is done by clippers or knives which sever it and cooperatingshear plate 20 onto a clipping 5 along lines generally lengthwise of thegrain. table 3.

In order to return the gauge finger a inaccurately and promptly to its gauging position, W g descnbed m thlsspeclficatlon and as following such a deflection, a light spring 4| moreparticularly defined by the claims which may be employed connecting anarm 42 on the 45 termmate the gauge finger 4 with a point on the supportfor In the accompanymg drawmg I have Shown in the gauge finger indicatedat 43.

To adjust the gauge finger of fingersvertically, that is, with relation to the surface of the table 3, thebar 5 is held in vertical guides, such as the slots 69' formed as partof the frame 6 of the machine, and is adjustable vertically by jackscrews El or equivalent means.

Each slide 45 carries an index pointer 41 which cooperates with a scaleor rule 1, likewise held in the frame 6, and extending parallel to thebar 5. For accurate adjustment of the finger 4 with relation to theclipping knife 2 the scale I is adjustable lengthwise, that is, in thedirection of the movement of the veneerstrip, and is held in adjustedposition by aset' screw As will now be evident, the gauge finger 4,which may swing in the directionthe veneer strip is advancing, ispositioned closely adjacent the path of movement of the veneer, butnormally sufficiently above it that it'will not be contacted and swungaside by minor irregularities inthe veneer strip. It isadjustedforspacing, that is, to gauge the width of the veneer strip tobe out 01f, withrelation to the scale I and by movement of the slide 45along the bar 5, and it may be adjusted vertically by means of the setscrews 61. Now as the advancing edge ofthe veneer strip reaches a pointin vertical registry with-the gauge finger 4 the clipping knife 2 isoperated'to sever the veneerstrip at this width, and unless the veneerstripis curled or warped it passes on beneath the gauge finger 4 withoutcontacting nor affecting the latter.v Should the veneer strip, either atits advanoingedge or intermediate its edges, be warped or curled, itwill engage the-veneer strip, which will be swung aside in oppositionto'the light tension of the spring. This does' not-occur during anygauging operation, only afterthe gauging operation has been completed.The finger 4, being short in lengthand light-in weight, hasno effectupon the veneer and does not retard it nor curl it further. Uponpassage. of the interfering portion of the veneer' stripbeyond thegauging finger the latter swings back to'its gauging position, where itisaccurately positioned by-the spring and stop means, such actionoccurring well in advance ofany further need for the gauge fingerengaging the'width of' the veneer strip. Thus the gauging operation'isconducted accurately, rapidly, and with: no interference nor damage-tothe veneer strip.- v

It will be observed'thatthe operation of the gauge finger is dueprimarily to the fact that it is light and resiliently mounted;

What I claim as my invention is? 1'. A gauge for use in'gaugingthe-width of a 1 for sliding adjustment strip of veneer or like flimsymaterial as it moves lengthwise of a table, preparatory to clipping suchstrip, comprising a bar above and extending lengthwise of the table, ascale disposed parallel to said bar, a member mounted on said barlengthwise of the bar, and carrying an index cooperating with saidscale, a finger pivotally depending from said member andhavingits lowertip lying above the normal level of veneer upon the "table, said fingerbeing swingable in the direction of movement of the veneer, whereby itmay be swung aside by a warped portion of the veneer, as the latterpasses, and means to adjust said bar vertically, to adjust the clearanceof the fingers tip above the-table.

2. A gauge for use in gauging the width of a strip of veneer or likeflimsy material as it moves lengthwise of a table preparatory toclipping such strip, comprising a bar above and extending lengthwise ofthe table, a scale disposed parallelto said bar, a membermounted on saidbar" for sliding adjustment lengthwise of the bar, and carrying an indexcooperating with said scale, a finger pivotally depending from saidslide, its lower tip lying above the normal level of veneer upon thetable, said finger being swingable in the direction of movement of theveneer, whereby it may be swung aside by a warped portion of thev'eneer,as'the latter passes, means to adjust said bar vertically, to adjust theclearance of the fingerstip above the table, and means mounting thescale-for lengthwise adjustment to accurately position samerelative' tothe veneer clipping means.

3. A gauge for usein gauging the width of a strip of veneer or likefiimsymaterial as it moves lengthwise of a table, preparatory to clipping-such strip, comprisinga bar above and extendinglengthwise of thetable, a member mounted on'said. bar for adjustment therealong, a gaugefinger depending from said member and having its lower end lying abovethe normal level of veneer uponthe-table; said gauge finger beingswingable in the-direction of movement of the'veneer so that it may beswung aside by a warped portion'of the veneer to permit the veneer topass by the'same; and means for vertically adjusting said:bar'toadaptthe gauge finger for use to gauge'veneers ofdifierent thicknesses.

4: A'gauge for use in gauging the width of a strip of veneer orlikefiimsymaterial'as itmoves lengthwise of a table; preparatory toclipping such strip, comprising a-bar above and extending lengthwiseof'the table, a scaledisposed parallel'to said bar, a member carried" bysaid bar and adjustable therealong, a gauge finger depending from saidmember,.an index carried by said member for cooperation withsaid scale,and means mounting said scale for lengthwise adjustment to accuratelyposition same relative to the veneer clipping, means.
